What is a porch?

A porch is a small extension built around the front door, giving a lobby for coats and shoes and stopping draughts reaching the hall. Most are brick with a pitched tiled roof to match the house, though glazed and timber porches are also common.
How much does a porch cost in North Watford?
In North Watford, a porch typically costs £7,000–£17,000 from a 3 m² porch to a small front extension, including VAT at 20% (standard rate). Building costs in the East of England run about 6% above the UK average, and the figures for North Watford are adjusted to reflect that. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| From a 3 m² porch to a small front extension | £7,000–£17,000 |
| Higher specification | £17,000–£21,000 |
The biggest cost drivers are:
- Whether building regulations apply
- Size and roof style
- Brick matching
- Moving meters, drains or the doorbell and lighting
Use the guide price tool to see how size and specification change the figure, then ask for a written, itemised quote.
Do you need planning permission for a porch in North Watford?
Before anything is built in North Watford, we confirm which approvals apply in England. In England a porch is permitted development if its ground floor area is no more than 3 square metres, no part is over 3 metres high and it is at least 2 metres from a boundary next to a road.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
